GoGyro™ 35
The fully integrated GoGyro is designed for simple and easy everyday use, no matter what the application.
The GoGyro is fully integrated with a built-in rechargeable battery.
Due to its incredibly low power consumption, the GoGyro can survey for up to 100 hours on a single battery charge.
TwinGyro™ 35
The rugged 35mm housing of our fully integrated TwinGyro features our unique technology of two gyros in one.
The TwinGyro is ideal for surveying where hole diameter is not an issue, and getting two surveys per run significantly cuts rig downtime. It is available in multiple configurations including overshot for easy use in coring.
The tool's modular design reduces both repair times and costs.
NorthFinder 35
Our NorthFinder is tailored for high performance under demanding conditions, all in a slimline 35mm package.
A high-accuracy FOG-based NorthFinder module is married with a continuous navigation MEMS module to provide the ultimate in versatility for your high-end survey applications.
Real-time processing is performed while the tool is running, allowing an ultra-high navigation sampling rate for superior accuracy and lightning-fast download and presentation of results.

SlimGyro™ 25
The SlimGyro is a fully integrated rate gyro survey instrument with a diameter of only 25mm, making it the world's slimmest.
With its incredibly low power consumption, the device can conduct surveys for up to 100 hours on a single battery charge.
The SlimGyro is an excellent tool for blast hole surveying due to its length of 140 cm and weight of only 3 kg.
The simple set-up saves valuable site-time and potential sources of human error are significantly reduced. The modular design of the tool minimizes repair times and cost.
SlimTwin Gyro 25
The SlimTwin, with its rugged 25 mm housing, offers our unique two-gyros-in-one technology.
With its low power consumption, the tool can survey for up to 50 hours on a single charge.
All versions of Inertial Sensing gyros can operate in standard multi-shot mode or fast continuous survey mode.
The simple setup saves valuable site-time and potential sources of human error are significantly reduced. The modular design of the tool minimizes repair times and cost.
BlastGyro™
The BlastGyro™ is a unique survey system designed for efficient surveying of production blast holes. At the heart of the system is the world’s slimmest survey gyro the integrated SlimGyro.
The lightweight and compact size of the system makes it safe and easy to manually run in and out of blast holes using a feeder reel fitted with 50 or 100 meters of fiberglass rod. The BlastGyro can survey at all angles and the fiberglass rod assures it can be moved up, down and horizontally.
Apart from blast holes the BlastGyro is also ideal for use in injection holes, grout and jet grout holes, canopy tubes, pilot holes, pile holes and more.

TrueDepth
With this market-leading innovation, we let the survey gyro measure its own depth in the hole! This is a true measurement, not a guess based on an estimation from the hole depth you tell it. The BlastGyro™ now knows exactly where in the hole it is without any hint from the operator. With this one innovation, we have made it simpler, faster, safer, and more accurate to perform high-density continuous surveys.
Compass 35
This Compass 35 tool is a magnetic multi-shot borehole surveying instrument that utilizes modern MEMS technology. It's integrated with brass running gear, making it quick to set up in the field.
The running gear is integrated and 35 mm in diameter. The tool comes with three aluminum extension rods which help move it away from the drill bit. The Compass 35 is easy to operate with a spearhead landing collar that has multiple sizes.
Compass 25
The Compass 25 records station depth, inclination, azimuth, a gravity high side, magnetic tool face, and temperature. The magnetometers are calibrated with high precision to deliver a reading of the local magnetic field's magnitude. This can help to identify anomalies in the Earth's magnetic field and survey stations of low quality.
The Compass now comes in a Slim 25mm housing, which is the perfect fit for AQ-sized or non-magnetic blast holes.
